I owned a PC45 one year and it is a decent stove but I have owned a Bixby for 6 years and like it better every year.
They each have certain advantages and in some circumstances the Harman is better and in other circumstances the Bixby is better.
Basically the Bixby will produce more heat in a larger area because of its larger convection fan.
The Harman's convection fan can be shut off for quiet time where as the Bixby fan has to run all the time but is pretty quiet on lower heat levels.
Noise of fan running can be compared to a refrigerator running-after a while you get used to it as white noise.
Speaking of noise the agitator on a Harman can be loud too. The Bixby makes noise when it dumps the clinker so I guess both produce some noise.
Both are proven reputable stoves that have been improved since they were introduced.
Bixby is not producing stoves but parts are available with very easy to understand directions if needed. Meaning they aren't really that difficult to repair. Many people have been helped with advice from others on IBC site so the idea of having to depend on a dealer isn't a problem. The consumer can buy parts from Bixby simply by calling. Try that with Harman they just tell you to go through your dealer. If your dealer dies what then? Will another dealer honor the warranty? Good luck with that.

Why are you thinking of replacing the pc45? I like the Bixby for the quick heat but I am installing a pc45 because I am getting it with a boiler kit to heat the basement floor. If the convection fan is weak I can find a way to upgrade
